This invention relates to handling apparatus for aerial lines and it is an object of the invention to provide an apparatus of this kind which operates to provide temporary support for an aerial line.

It is also an object of the invention to provide an apparatus of this kind adapted for use in hot line maintenance and which is used to provide temporary support for such line nt in connection with permanent support for such line and which also holds theline in a position out of the way of the workman.

An additional object of the invention is to irovide an apparatus of this kind of a portv able type .h ch includes a support tor a line to 'og er with means comprised in such sup port for operating a tong to move or shift a line, such as a high tensioned conducor the like, as may be required during intenance service.

The invention also has for an object to rovidc an app atus of this kind adapted for so in connection with electrical transmision lines and which is adapted to provide mporary support for such lines as may be aired by maintenance service without any interruption to the line service an ii manner whereby danger to the workman is reduced to a minimum.

T he invention consists in the details of construction and in the combination and arrangement of the several parts of my improved handling apparatus for aerial lines whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and ad'- vantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will her c... rafter be definitely claimed.

in order that my invention may be the better understood, 1 will now proceed to de scribe the same with reference to the accompanying drawings, wherein Figure 1 is an elevational view illustrating an apparatus constructed in accordance with an embodimei'it of my invention, one of the tongs being indicated by full lines and a second tong being indicated by broken lines;

tially on the line 66 of Figure 4.

As herein disclosed, my improved apparatus comprises an elongated supporting member 'orbar 1 herein disclosed as angular in cross section and which is provided at each extremity with a cylindrical extension 2 directed through an eye member 3 carried by a bracket B. Engaged with the extension 2 outwardly of the applied eye member 3 is a holding nut l or its equivalent.

Each oi the brackets B comprises perpendicularly related arms or plates 5 terminatin outwardly disposed extension arms 6 and 6. The extension arm 6 has its outor portion arcuate in form, said arcuate portion being provided with a longitudinally disposed closed slot 7 while the second extension arm 6 is provided with a longitudinally disposed slot- 8 open at the outer end of the extension arm 6. W hile not always essential, in practice I find it desirable to have the extension arms 6 and 6' of one bracket reversely related with such extension arms of the second bracket B,

Disposed through the slot 7 is the shank of an eye bolt 9, said shank having engaged therewith a wing nut 10 contacting from without with the arcuate portion of the extension arm 6. Secured to the eye bolt 9 in a conventional manner is end portion of. a flexible member 11, herein disclosed, as a chain, the opposite end portion oi the chain being adapted to be adjustabl connected, as occasions may demand, with the extension arm 6' by inserting a link of the chain 11 ithin the slot 8.

i /hen the brackets B are applied to a conventional wooden pole P the outer or free end iii portions of the arms 5 of the brackets B will bite into the pole, thus further assuring the brackets being eiiectivoly maintained in applied position upon requisite tightening of the members 11. The relative a 'rangcment oi the arms 5, however, also permits the brackets to be operatively engaged with an angle member or beam 12 such as is comprised in the tower structure supports for high tensioned transmission lines.

As herein disclosed, the member or bar 1 has slidably engaged therewith a plurality of yokes 11. In the present embodiment of my invention the yokes are three in number with two adjacent vokes disposed in opposite directions and tire third yoke extending outwardly from the member or bar in perpendicular relation to the first mentioned yokes. This arrangement is provided to readily perinit the desired handling 05 number 01"? lines.

As herein set forth, each of the yokes A comprises a plate 1: of requisite dimensions having its side faces disposed in the same general direction as the nember or bar 1. The inner ed re 01 the plate 1% is provided therealong wth a groove or channel 15 of such cross sectional configuration to snugly receive a corner portion of the member or bar 1. The opposite end portions of this grooved or channeled ed go of the plate let are provided with the outstanding cuffs or sleeves 16 which have snugly disposed there through the member or bar 1. By this means each of the yokes A is etlectively held to the member or bar 1 yet is free for movement or adjustment lengthwise of said bar or memher 1.

The outer portion of the plate 1% of each of the yokes A is provided with the jaws 17 spaced apart similar to the cuffs or sleeves 16 or in a direction lengthwise of the member or bar 1. Que of said jaws 17 has pivotally connected with its outer extremity a retaining dog 18 herein disclosed as in the form ot a link. This dog or link 18 is of a length in excess of the space between the outer end portions of the 17 and thereby permitting ready entrance but normally closing such space and particularly against withdrawal. This dog or link 18 operates by gravity and it is, therefore, to be noted that it is operatively engaged with the upper of the two aws 17.

Between the jaws 17 is adapted to be engaged an eye member 19 carried by an end portion of an elongated line tong or gin pole T. This tong or pole is of desired length and is provided at its outer or free end with a clamp C adapted to be engaged with the line to be manipulated.

The upper portion of the plate 14 01" each the yokes A, as herein disclosed, is provided with an opening 20 to permit convenient coupling therewith, as by a hook 2 1, of a cable 22. This cable 22 is disposed, when the apparatus is in assembly, over a guide member 23 suitably supported above the uppermost bracket B. As herein disclosed, this guide member 23 constitutes a pulley adapted to be suspended from the upper portion of the pole P or more particularly from a cross arm 24:.

The outer portion of the tong or pole T is provided vith an eye member 25 with which is engrgec, as by a hook 26, a second cable 27. This cable 27 is operatively engaged with a guide member 28 preferably a pulley supported by the pole P at a point above the uppermost bracket B. These cables 22 and 27 are oi such length as to be readily manipulated from the ground. The hook 20 and the cable 27 have preferably interposcd therebetwecn an insulated link stick in practice, when it is desired to move he lines L to replace an insulator bracl'cets B are operatively engaged .i the desired pole or kindred supportand a tong or pole T -s ope 'atively engaged with a suitable yoke A and with the line L to be removed from such insulator. Pull is then imposed upon the cable 22 to move the yoke upwardly, such movement resulting in a lift- 1e line L and a movement of such 1 cwardly from the pole P or rindred support, or more particularly the cross arm After the yoke has been moved upwardly to substantially the limii; of such movement a cotter pin 31 or the like is dicted through a suitably positioned opening in the member or bar 1 to maintain the yoke in such raised position.

When 1' is desired to again tie the line L to the replaced insulator, pull is imposed upon the cable 27 to swing the tong or pole T inwardly a distance sutlicient to bring the line L substantially directly above the insulator. The cot'ier pin 31 is then removed and the yoke permitted to drop or move downwardly to bring the line L in proper position with respect to the insulator to permit the same being conveniently tied thereto.

The cable 27 also provides an efiective means for limiting the extent of side swa of the line 1 when released. This cable may be engaged with suitable support at the ground provided the working operation is enpecled to take too long a time for the cable to be held by workman an. under certain conditions, particularly in connection with light work, the cable may be suitably engaged with the pole P for limiting th side sway of the line.

By having'the yokes A arranged as hereinbet'ore stated, it will. be obvious that the insulators at either side 01 the pole or kindred support or directly th reabove may be readily and conveniently replaced as may be desired.

lVhen it is intense-cl to remove tile cross arm 24, atong or pole T is engaged with each of the lines L supporled by the pole P lit) or the like, it being understood that in the assembly of my apparatus there will be a number of yokes A. equal to the numb'-r of lines The tong or pole coacting with he line substantially directly above the pole P or .he like assumes substantially a vertical position and must, therefore, be held against any undue lateral swinging movement. In order to avoid any such undue lateral swinging movement, I find it of advan'. age to apply to the pole P or kindred support at a desired distance above the upper bracket B an eye member 33, or il -ring as known in the trade, and through which the tong or pole is freely inserted.

With the use my improved appara'lus it is to be noted that the stress of the line supported b T the tong is imposed through the tong directly upon the yoke, said long constituting a column having an end abutting the yoke, thus assuring a maximum of holding resistance. This is further assured in view oi the fact that the long or pole P is free of longitudinal shifting or yield independently of the coacting yoke A.

This efiiciency is accomplished due to the fact that the tong or pole l constitutes a rigid member and swinging movement with respect to the yoke it about fixed fulcrum.

From the foregoing description it is thought to be obvious that a. handling apparatus iior aerial lines constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invent-ion is susceptible oi: some change and nodification without departing from the principles and spiritthereot' and for this reason I do not wisn to be understood as limiting myself to I he precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
